DefinitionThis section has been translated automatically.
Polyethyleneimine, acronym "PEI", is formally the polymerization product of its monomer ethyleneimine (aziridine). When ethyleneimine is polymerized by ring-opening polymerization, a strongly branched polymer molecule PEI-7-PEI-2000 is usually formed. The number after "PEI-" indicates the average number of monomer units - CH2-CH2-NH-.
